CONCRETE-SPREADING OI-IUTE.

Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed November 13, 1912. Serial N 0. 731,113.

To all whom it may concern Be it known that I, WVALLAoE C. MOANLIS, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and'State of Ohio, have invented a new and useful Improvement in Concrete-Spreading Chutes, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to'distinguish it from other inventions.

My invention relates to chutes for distributing material, and particularly to chutes adapted to spread concrete.

The object of my invention is to effect such distribution in an economical and efiicient manner, a specific object being to eliminate as largely as possible the necessity for shifting theposition of the source of the material or reservoir containing same, Which is usually coincident with a change of location to which it is desired to conduct such material.

The said invention consists of means hereinafter fully described and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.

In said annexed drawing: Figure 1 is a plan of a chute embodying my invention and particularly adapted for use in connection with a concrete mixer, an accepted or usual type of such mixer being also shown in plan in said figure. Fig. 2 is a side elevation of the said device and mixer. Fig. 3 is a transverse section taken upon the plane indicated by line IIIIII in Fig. 2. Fig. 4.- is a perspective view of one of the chute elements embodied in my invention.

In the illustrated form of chute embodying my invention, the latter consists primarily of two main elements, a frame-member and a trough-member. The frame-member consists of two side rails A A which are supported at their ends by brackets B B which latter are adapted to rest upon the ground or other suitable foundation. These side rails are preferably of angle form as shown, in which one of the legs of the angle member is vertical and the other extends outwardly at right angles thereto as shown in'Fig. 3. The upper bracket B may be provided with a circular aperture 6 which forms a bearing for a swivel pin C suitably secured, whereby the entire chute may be swung about an axis passing through its upper end. By this means it will be seen that the discharging end of the chute may be shifted as desired within certain limitatlons. A suitable hopper B is secured to the upper end of the chute and directly receives the discharge of concrete from the mixer D.

The trough-member of the chute consists of a plurality of members E which are supported upon the side rails so as to form an imbrication. The rear or upper end of each element E is oscillatorily mounted upon the side rails in any suitable manner whereby it may be swung upwardly as shown in Fig. 2 to form an opening in the trough, or downwardly to close such opening. The lower orfront end of each element is provided with two laterally extending projections e e, as shown in Figs. 1 and 4: which are secured near the upper plane of the element and which normally rest upon the upper surface of the side rails, that is they so rest when the element closes the opening which it forms when swung upwardly. These projections rest freely upon and extend laterally beyond the side rails whereby they may be conveniently used as handles for raising the elements. Forming an imbrication, these elements overlap each other as shown in Fig. 2, whereby fluid may be caused to pass downwardly through the trough Without leaking between the joints, as will be readily understood.

The elements E consist preferably of sheet metal and are of U-shaped cross section with a reinforcing band 6 which is intersected by the axis of oscillation. This reinforcement placed in this position provides a strengthening element immediately adjacent to that point of suspension of each element which is subject to the greatest strain, as will be readily understood by those skilled in the art.

By means of the above described construction it will be seen that a plurality of points of discharge may be formed in a given chute, any one of which may be formed by simply raising the corresponding element E. In this manner the concrete may be delivered at various points longitudinally along the chute,

without changing the position of the mixer.

The necessity for changing the position of the latter is therefore minimized, depending of course upon the length of the chute, which may be made as desired within certain limitations.

Having fully described my invention, what I claim and desire to secure'by Letters Patent is a l. A concrete-spreading chute comprising the combination with a frame-member; of a plurality of elements each having its opposite sides supported by said frame-member; each element having an axis of oscillation in tersecting its upper or elevated end and oscillatory independently of the other elements; all of the latter together adapted to form a chute.

2. A concretespreading chute comprising the combination with a frame-member; of a plurality of elements mounted upon the latter to form a trough; each such element having its upper end intersected by an axis of oscillation, the sides of the other end resting freely upon said support; each of said elements being oscillatory independenly of the others.

3. A concrete-spreading chute comprising the combination with a frame consisting of end brackets and two side-rails mounted thereon; of a plurality of trough elements each having its upper end oscillatorily mounted upon said side rails; the lower end of each element being provided with laterally extending supporting-members loosely resting upon said rails; each element being oscillatory independently of all of the others.

4. A concrete-spreading chute comprising 7 the combination with a frame-member; of a plurality of elements each having its opposite sides supported by said frame-member; each element having an axis of oscillation intersecting its upper or elevated end and oscillatory independently of the other elements; the upper of said elements overlapping the lower and adjacent elements, whereby each of the latter is upwardly tiltable; all of the elements together adapted to form a chute.

5. A concrete-spreading chute comprising the combination with a frame consisting of end brackets and two side-rails mounted thereon; of a plurality of trough elements each having its upper end oscillatorily mounted upon said side-rails; the lower end of each element lying upon the upper end of the adjacent element and being provided with laterally extending supporting members loosely resting upon said rails; each element being upwardly tiltable independently of all of the others.
